The rcar DT overlays are missing symetrical remote-endpoint properties in their graph nodes because the remote-endpoint is fixed up at run-time. Disable the dtc 'graph-endpoint' warnings when compiling these overlays. If this becomes a common problem for overlays, then perhaps this check needs to be disabled for all overlays.
